Seagate Hard Drive Firmware Failure:

Seagate Barracuda 7200.11 Firmware Failures:

Seagate Firmware.

You may note problems with your Seagate Barracuda  7200.11 hard drive  family model hard drive. The reported problem has shown specific Seagate hard drive  failures reporting a  0 GB size or not show up in BIOS during a post. This means your data stored on your failed Seagate hard drive will not be accessible until the Seagate hard drive failure is “repaired”.

The Seagate Barracuda 7200.11 firmware failure is typically a result of critical firmware modules that have become damaged. The table below shows the affected Seagate Barracuda 7200.11 model that may be affected.

Seagate Barracuda 7200.11   ST3500320AS AD14, SD15, SD16, SD17, SD18, SD19, SD81 SD1A
Seagate Barracuda 7200.11   ST3500620AS AD14, SD15, SD16, SD17, SD18, SD19, SD81 SD1A
Seagate Barracuda 7200.11   ST3500820AS AD14, SD15, SD16, SD17, SD18, SD19, SD81 SD1A
Seagate Barracuda 7200.11   ST3640330AS AD14, SD15, SD16, SD17, SD18, SD19, SD81 SD1A
Seagate Barracuda 7200.11   ST3640530AS AD14, SD15, SD16, SD17, SD18, SD19, SD81 SD1A
Seagate Barracuda 7200.11   ST3750330AS AD14, SD15, SD16, SD17, SD18, SD19, SD81 SD1A
Seagate Barracuda 7200.11   ST3750630AS AD14, SD15, SD16, SD17, SD18, SD19, SD81 SD1A
Seagate Barracuda 7200.11   ST31000340AS AD14, SD15, SD16, SD17, SD18, SD19, SD81 SD1A

If your Seagate Barracuda 7200.11 hard drive is physically failing, then the critical firmware region of the hard drive may not be accessible because the sectors where the firmware is stored has developed damaged sectors. When this happens, the hard drive may not be accessed since the firmware zones are corrupted or damaged.

The end result, the Seagate hard drive will not be recognized in BIOS and your computer will not recognize your failed Seagate hard drive in any type of Device Manager or  utility.

There are several references describing how to access a failed Seagate 7200.11 hard drive. One method suggests updating the corrupted Seagate firmware.  Another method suggests manually repairing the corrupted Seagate hard drives via HyperTerminal.

Attempting to repair the corrupted Seagate firmware modules via HyperTerminal when the Seagate hard drives have significant damaged sectors in the firmware zone will NOT work.

The scope of this type of repair is well beyond the ability of most individuals attempting to do their own Seagate data recovery: This is because the complexity of this type of  Seagate Barracuda 7200.11 failure involves a special technique whereby the corrupted firmware must be bypassed.

If your data is critical, then writing to your failed hard drive can be risky and can result in corrupted data and or permanent data loss. So take all necessary precautions before you experiment with your failed Seagate Hard Drive.

In several cases, some suggested repairs do work, and your data is recoverable, but there are always risks to consider before you attempt your own Seagate data recovery.

Before you attempt your own Seagate data recovery:

1 – Find out if your hard drive model and firmware are affected.

2 – Determine if your hard drive has physical damage to the sectors where the firmware is being stored.

3- Determine if your hard drive is clicking.

4- Establish if your hard drive motor is spinning.

5- Determine the value of your data and ascertain if you are willing to Risk your  data by attempting solutions that you are not familiar with if you are not a data recovery expert.

If your hard drive is clicking, or your hard drive motor does not spin up, or you have bad sectors in critical hard drive areas, then you need to consider using a data recovery professional. If you data is critical and you need help, you can always contact us via email or phone.

Water Damaged Hard Drives.

Water Soaked Hard Drive After A Hurricane or Flooding:

Not sure what to do…THEN DON'T DO ANYTHING Yet!

Don't Let Your Wet Hard Drive to Dry!

Don't Power On Your Wet Hard Drive. 

Traces of  salt or foreign matter in your hard drive is all that is needed to permanently scratch or corrode your platters and DESTROY your DATA.

We have had many calls with regard to the East Coast Flooding. Therefore, RMD thought we should share some of our knowledge on what TO DO and what NOT TO DO if your hard drive gets wet, soaked or contaminated after a hurricane or major flood.

What Happens When Hard Drives Get Flooded or Wet?

Here are the major challenges that a user will experience when a hard drive is damaged by water, dirt or any foreign matter.

Firstly, a main issue is that water has many dissolved salts present in it: Salts dissolved in water will vary from state to state, and also by locality. For example, water form New Jersey, New York, Connecticut, Virginia or any other state will vary in salt composition. The location where your hard drive got wet or flooeded dictates what type of salts will crystallize on your hard drive when your wet hard drive is left to dry. This means the data recovery process on hard drives will vary based on the type of salts found on your flooded or wet hard drive.

Salt Deposits on Hard Drives after Flooding:

Depending on your location, as the water evaporates from your flooded hard drive, the dissolved salts begin to concentrate and leave crystalline deposits or films on the surfaces of the wet hard drive platters, motor, hard drive heads and the head assembly. If you turn the wet hard drive on after the hard drives has been left to dry, then the salts will make contact with the heads/magnets and most likely scratch or damage the platters permanently, thus making your hard drive non recoverable.

If dirt or any foreign matter is mixed with the water and contaminates your hard drive, and you proceed to dry your hard drive and turn your hard drive on, then you are essentially left with no alternatives. You data will NOT be recoverable.

Salts on a Hard Drives Printed Circuit Board – (PCB).

Distilled or deionized water are not good electrical conductors. Many dissolved salts in water tend to be good to moderate electrical conductors. Salt water (Na Cl – Sodium Chloride) is an excellent electrical conductor. Therefore, we must always remember that when your hard drive gets wet from a flood it can potentially short out your hard drives' PCB. This means a once simple wet PCB can essentially result in a damaged hard drive heads.

Cleaning Flooded Hard Drives:

Once this process is completed, RMD evaluates the condition of the hard drive surface and the internal hard drive components with a high powered microscope to determine if the wet contaminated hard drive needs additional cleaning or if it is ready to be repaired, powered on to run diagnostics and prepare to initiate the data recovery imaging process.

Our advice is as follows:

If your hard drive got wet or flooded, then you should leave it wet. Place your wet hard drive in a sealed baggie or plastic bag and send it to RMD in water ASAP. The reason for this is the hard drive will not dry out, therefore the salts can not crystallize out and deposit onto the hard drive platters or the other internal hard drive components. RMD can then apply their propriety hard drive data recovery process to remove crystallized salts and foreign matter from the hard drive heads, magnets, motor and platters.

Not sure what to do…THEN DON'T DO ANYTHING!

Call RMD FIRST, we will at least make sure you don't risk or further damage your wet or flooded hard drive.
